无核白葡萄在果实生长发育期间，果实的增大主要在其生长前期和转熟后的一段时间；果实转熟后，糖分积累明显加快，有机酸含量迅速下降；果实中N、Ca、Mg、B含量在其发育的前期最高，随着果实的膨大，各元素浓度呈下降趋势，但变化幅度趋缓。K的浓度在果实转熟期后，随着糖分的增高而升高。单果中各元素的含量在不同发育期内总体表现为增高趋势。
During fruit growth and development, the increase of fruit mainly occurred in the period of pre-growth and post-ripening. After ripening, the accumulation of sugar increased obviously and the content of organic acid decreased rapidly. The contents of N, Ca, Mg , The content of B was the highest in the early stage of its development. With the enlargement of fruit, the concentration of each element showed a downward trend, but the variation range slowed down. K concentration in the fruit maturity, with the increase of sugar increased. The content of each element in the fruit in different developmental stages showed an overall increase trend.
